They say ~ "Creates smooth lines that are defined and precise. Smudge-proof, budge-proof and water-resistant coverage for all day wear to combat against, sweat, tears and rain!"
This product does what it says in the tin, it is long lasting although with my eyes it does seem to transfer a little on to the upper lid. But if you set with a powder this doesn't seem to happen as quickly. A matte finish to this one. I also really like the little angle brush that comes with the eyeliner.
